How to Fit a Moza Wheel to a Simucube Wheelbase

A few weeks ago, I reviewed the impressive Moza Vision GS wheel. As the review mentioned, I thought quite highly of Moza’s first high-budget wheel. Anyway, to give the wheel a fair test, I fitted it to my Simucube 2 Pro instead of the Moza R3 (or my R5). The reason was pretty simple: I wanted a higher torque and FFB detail experience to give the wheel a fair comparison to my other favourite wheels.

In today’s short post, I’m going to explain how I fitted the Moza hub to my Simucube, as it’s not quite as trivial a job as you might think.


Moza sells a Universal Hub Kit, which comprises a hub adapter for their NRG style bearing based hub, drilled to 50mm and 70mm PCD bolt patterns.

While it’s tempting to look at their product page and leave with an understanding that the hub kit allows Simucube compatibility, it does not.

Spot the error:

The image featured in the red box is, of course, the wheelside SQR hub for a Simucube. But the wheel side and wheelbase hub sides are different. Simucube uniquely uses an imperfect triangle to mount the SQR wheelbase plate to the wheelbase.

If you inspect the Moza hub plate adapter, it does have a triangular fitment, but, it is not Simucube compatible. (I tried!).

The “fix” is very easy – convert the Simucube to a 70mm PCD fitment with this handle little plate adapter from Sim Racing Machines, then fit the Moza adapter.

As you can probably tell, this plate uses Simucube’s irregular fitment to attach to the base and offers you a threaded 50mm or 70mm PCD fitment. Very handy.

Here’s how it all goes together:

Remove the 3 bolts that hold the SQR plate together. Always use a good hex / Allen key set. Mine is a Draper set – cheap tools slip in situations like this and then you’re in a world of problems.

If you’ve ever wondered what’s behind the SQR plate on a Simucube, here you go. In the centre, you can see the motor shaft. Attached is a collar clamp. It’s a nice solution and I’m still firmly of the belief that the SQR is one of the best ways to attach a wheel to a MiGE based servo motor.

Occasionally, the collar clamp can come loose (this is a rare issue with a Simucube) so do take the opportunity to check the tightness of the bolts while they’re exposed.

Next, attach the SRM plate adapter:

Once you’ve fitted the PCD adapter plate, you have 50 or 70mm PCD compatibility on your Simucube. Happy days! Finally, fit the Moza hub adapter:

You’re now ready to mount your Moza wheel, remembering of course, that you’ll need the USB adapter for the wheel to function. Here’s my installation, ready to go:
